Perhaps you should try some spelling variations:
"programmed well death" » "programmed cell death", "programmed cells death", "programmed below death", "programmed well heath", "programmed cell deaths"
"programmed self death" » "programme self death", "programmed cell death", "programming self death", "programmed self data", "programmed self heat"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"programmed well death\") OR (\"programmed self death\"))".
• Removing quotes may allow a broader search: (( programmed well death ) OR ( programmed self death )).
• Adding a wildcard symbol may retrieve word variants: (("programmed well death") OR ("programmed self death"))*.
